/etc/localtime is a _text_ file, containing the name of the timezone;
/etc/timezone is a symlink to the corresponding _binary_ timezone
file.

The code in lib/Sys/Info/Driver/Linux/OS.pm just reads the text from
/etc/localtime currently; replacing it with /etc/localtime therefore
won't work.

Is there any facility to get the name of the timezone out of
/etc/localtime (short of following the symlink and mangling the
target file name)?


Cheers,
